I got gdb attached to the running parent process and let it continue this is in a screen so i should be able to get you more info on the next crash. i have tgt setup with about 5 machines mounting different targets. right now its single head attached to a dell md3k using multipath to the array. targets are being presented over lvm, and initiators are simply mounting these file systems(mostly xfs some ocfs2). This is centos5 running a vanilla kernel i/o is fairly light, but there may be some network latency in play here (we have been having issues with some switches). this box also serves up some a few filesystems over nfs. plenty of mem / cpu / net.. dual quad core, 8g of mem 2 gig-e interfaces bonded using 802.3ad i am trying to think of anything that may be helpful:) the modules loaded are: # lsmod Module Size Used by dell_rbu 39968 0 ipv6 289864 34 ipmi_devintf 41616 2 ipmi_si 72044 1 ipmi_msghandler 63832 2 ipmi_devintf,ipmi_si bonding 112888 0 binfmt_misc 41868 1 nfsd 279720 17 lockd 96080 1 nfsd nfs_acl 35584 1 nfsd auth_rpcgss 70816 1 nfsd exportfs 36864 1 nfsd sunrpc 211656 86 nfsd,lockd,nfs_acl,auth_rpcgss scsi_dh_rdac 38788 3 dm_round_robin 35584 1 dm_multipath 48024 2 dm_round_robin scsi_dh 39172 2 scsi_dh_rdac,dm_multipath fan 37768 0 container 36608 0 battery 45192 0 acpi_memhotplug 38276 0 ac 37640 0 usbhid 52548 0 hid 68672 1 usbhid thermal 51104 0 button 39968 0 processor 72376 9 thermal dcdbas 40240 0 usb_storage 145056 0 i5000_edac 41224 0 dm_snapshot 48456 2 dm_zero 34560 0 dm_mirror 49152 0 dm_log 41860 1 dm_mirror dm_mod 84848 207 dm_multipath,dm_snapshot,dm_zero,dm_mirror,dm_log ehci_hcd 64396 0 let me know if there is anything else, and thanks heaps ahead of time :) On Thu, Dec 11, 2008 at 8:05 AM, FUJITA Tomonori <fujita.tomonori@xxxxxxxxxxxxx> wrote: > On Thu, 11 Dec 2008 07:58:30 -0800 > "Jesse Nelson" <spheromak@xxxxxxxxx> wrote: > >> were running vanila 2.6.27.4 kern with tgt 0.9.2 with about 30 >> targets and about 10mb/s throughput >> i am constantly (daily) seeing tgtd segfault. no real deep info just >> this error in the logs: >> segfault at 8 ip 000000000040ebed sp 00007fffb259cb30 error 6 in >> tgtd[400000+23000] >> any ideas or suggestions how i can dig deeper here ? > > Can you run gdb with tgtd? > > If you can't, can you give the very detailed information about what > you are doing, which enable me to do the same thing you do to > reproduce the problem. > > Thanks, > -- To unsubscribe from this list: send the line "unsubscribe stgt" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
